Bernina in their wisdom have two modern day model 570QE. There are some differences that allows you to be sure you know which you have.
The current 570QE has been available since 2017. It has the new Bernina Hook and has the jumbo bobbins which are big & black. The stitch width is 9mm so the foot #1C is the standard foot. The newer models also have the dual feed and the hover facility.
The original 570QE has the traditional CB bobbin system so uses the metal bobbins with 7 holes. It has a stitch width of 5.5mm and the standard foot is #1.
If you are still in doubt the chassis number on the back will have the code LUN for the older 570 and VIO for the newer.
